Patent GB-345521-A (GB)
Title: Improvements in or relating to compositions of matter and articles or products obtainable therefrom
IPC: C08L57/00
Filed: 1930-04-10
Abstract: Comprises compositions containing a cellulose derivative and a polymerized vinyl compound, in proportions which are not by themselves compatible, and a natural or synthetic resin compatible with the cellulose derivative.  The addition of the resin renders the other constituents compatible.  Cellulose derivatives specified are the nitrate, acetate, formate, propionate, butyrate or other ester, and methyl, ethyl, benzyl or other ether.  Vinyl compounds specified are the polymerized acetate or halides, and styrene.  These are preferably used in the hardest form obtainable by polymerization. Synthetic resins specified are fusible and soluble phenol-formaldehyde resins made with acid catalyst, diphenylol-propane formaldehyde resins, benzene-, toluene-, and xylene-sulphonamide formaldehyde resins, lactic acid resins, and phenol-, acetone-, and aniline-furfural resins.  Natural resins specified are accaroids and guiac.  Small proportions may be added of resins not completely compatible with the cellulose derivative, e.g. manilla, pontianak, kauri, dammar, rosin, shellac, and ester gum. The compositions may contain plasticizers, softeners, solvents, pigments and dyes. Plasticizers specified are diethyl phthalate, dibutyl tartrate, triacetin, ethyl-toluene sulphonamide, and diphenylol-propane. Solvents specified are acetone, alcohol, benzene, methylene chloride, ethylene dichloride, ethyl lactate, tetrachlorethane, ethylene glycol monomethyl ether, dioxane, benzyl alcohol, and diacetone alcohol.  The solutions may be used as lacquers, varnishes, or coating compositions for metal, glass, fabric, &c., for making photographic or other films, for making filaments, and as adhesives for making reinforced glass &c.  The compositions may be used as mouldpowders, or worked up into transparent blocks or sheets which may be used in making reinforced glass.  In one example, the composition consists of 100 parts of polymerized vinyl acetate, 30 parts of diphenylol-propane formaldehyde resin, 30 parts of cellulose acetate and 300 parts of acetone.  In other examples, additional solvents are used with smaller proportions of the cellulose and the formaldehyde derivatives, or with toluene-sulphonamide formaldehyde resin and diethyl phthalate in place of the diphenylol compound. Specifications 308,658, and 311,657, [both in Class 95, Paints &c.], are referred to.ALSO:Comprises compositions containing a cellulose derivative and a polymerized vinyl compound, in proportions which are not by themselves compatible, and a natural or synthetic resin compatible with the cellulose derivative.
